$PEGIFICATI N forming part of Letters Patent No. 702,339, dated June 10, 1902.

Original application filed March 29, 1900, serial No. 10,656.

To all whom it may concern-.-

Be it known that LSIDNEY GEORGE BROWN, electrician, a subject of the Queen of Great Britain, residing at 7 Putney Hill, Putney, in the county of Surrey, and lately residing at Van Buren, Poole road, Bournemouth, in the county of l-Iants, England, have invented certain new and useful Improvements in Telegraphic Apparatus, of which the following is a specification.

This invention relates to improvements in electric-telegraph apparatus and refers to an automatic tape-punchinginstrument adapted to be operated by the signaling-currents received from a cable or line for punching signaling-holes in a tape.

The arrival currentsfrom a longcahle-section worked at fast siphonrecorder speed are of such a nature that when working over a long cable-section if a succession of impulses of the same polarity and of equal strength and duration be applied to one end of such section the first of such impulses will carry the tongue of the relay situated at the opposite end of such section againstits mark; ing-stop or contact. The variation in the strength of the received current due to the remainder of said succession of impulses is,- however, so small that the said tongue is not permitted to fall away from its marking-stop and break contact between the succeeding impulses of the same polarity and of equal strength and duration, as it ought to doin order to correctly reproduce the original signals. Then the polarity of the currentsent is reversed, the tongue of the relay responds readily, however, and is carried over to its opposite stop or contact, where it again remains without breaking contact between successive impulses of the same polarity and of equal strength and duration.

This invention has for its object punching apparatus which is adapted to be automaticallyoperated by signaling impulses received at siphon-recorder speed from a cable or line section in such manner as to punch signaling-perforations in a tape after reinserting or interpolating the impulses that have been lost, as aforesaid, so as to assure accuracy in the reproduction of the signals.

According to my invention one or other of Divided and this application filed January 30, 1901. Serial (No model.)

a pair of electromagnets is energized by the received signaling currents, accordingly as such currents are of positive or negative polarity. The electromagnet thus energized attracts one of a pair of armatures. The armature thus attracted is adapted to release one of a pair of clutch-sleeves, which released sleeve is then thrown into gear with a rotatingspindlc. The clutch-sleeves are frictionally attached to the rotary spindles. A third rotary spindle is similarly provided with a clutch-sleeve and is placed between the two aforesaid spindles. The two side sleeves when released by the armatures disengage and stop the central clutch-sleeve and operate the punches for making the perforations corresponding to the positive and negative impulses and at the same time make a central row of perforations in the tape. The central sleeve operates a punch for perforating the paperstrip of tape with a central row of spacing-holes when no signaling impulses are received. To prevent an inconvenient length of blank tape being manufactured by the central clutch and punch when no signals are received, a stopping device is arranged to come into operation, so as to disengage and stop the said clutch and punch after a definite number of central holes have been punched in the tape. Upon the receipt of a signal this stopping device is thrown out of action, and the stop is set back to zero. sleeves are adapted when thrown into gear with the rotating spindles to operate the punches at the same rate as that at which the contact-levers of the original transmitting instrument are oscillated, so that the number of signaling perforations punched in the tape will correspond to the number of impulses sent by the original transmitter,-notwithstanding the fact that the variation in the strength of the received current due to a series of impulses of the same polarity and of equal strength and duration may be insutficient to release the armature, and thereby arrest the clutchsleeve during the space of time between each of such series of impulses.

The clutch-sleeves are provided with teeth which are adapted to gear with similar teeth carried by collars on the rotary spindles. Suitable springs tend to force the clutch These clutchsleeves into gear with the collars. The cl utchsleeves are also provided with laterally-projectingpins, which rest upon the fixed lifting-rollers or equivalent devices when the said sleeves are at rest, and thereby raise the sleeves (against the pressure of springs) out of gear with the rotary spindles. When the armatures are attracted by their magnets,

they release the pins of the side sleeves, whereupon the latter are thrown into gear with the rotary spindles by means of the springs. The pins of the central clutch-sleeve are automatically engaged by a stopping devicewhen either of the side clutch-sleeves are rotating and also after a given length of blank tape has been punched when no signals are received. The clutchsleeves are provided with cams or their equivalent for operating the punches.

The spindles are caused to continuously rotate by any convenient means, such as by an electromotor provided with a governor to keep its speed constant.

Referring to the drawings, Figure 1 is a plan, and Fig. 2 is a side elevation, of the apparatus with the punches removed. Fig. 3 is a side view of the punches. Fig. 4 is a section on the line y of Fig. 1. Fig. 5 is a view of the levers V V 1) 12 at right angles to the view shown in Fig. 1.

The strikers P, S, and R respectively operate the punches P S R of the punching apparatus.

T is a ratchet wheel which is mounted loosely on a stud or axle t, journaled in the instrument frame or bed, and is provided with a coiled spring 15', which tends to rotate the said ratchet-wheel in the direction of the arrow in Fig. 1.

t is astnd which projects from the Wheel T.

t is a lever which is fixed on the stud't and carries a spring-pawl 17, adapted to engage.

with the teeth of the wheel T. 7

t is a lever connected below the baseplate of the apparatus to the stud t and connected by a link 3 to one arm of the lever s, also situated below the base-plate.

i is a spring-pawl which engages with the ratchet-wheel T and is adapted when in such engagement toprevent any return movement of the said wheel.

i is a fixed stop arranged in the path of the stud F. The pawls t t are provided with pins if t, which project into the path of a bar U. The bar U is fixed to one end of a rod it, which has its opposite end connected to one end of a pivoted lever it and is supported from the bed of the instrument by a link "a "a is a spring which tends to draw the rod u and bar U toward the wheel T and also presses the other arm of the lever it against a roller carried by one arm of a pivoted lever V.

. V is a pivoted lever one arm of which is secured to a spring v and the other arm of which carries a projection v upon which one arm of the lever V bears.

'u is a pivoted lever one arm of which is situated above the base-plate and carries a roller-bearing upon one end of the lever V. The otherarm of the lever c is below the baseplate and is connected by a link *0 to the arm 0 of the lever O.

o is a pivoted lever one arm of which is situated above the base-plate and bears on one end of the lever V. The other arm of the lever 41 is situated below the base-plate and is connected by a link 01 to the arm q of the lever Q. The projection o is adapted to be ,moved into the path of the pin m as hereinafter described.

The punches are carried by a suitable frame W, which latter also carries a slot or guide to for the paper tape. The central punch S is fixed to a plate 10, adapted to slide on guide-rods 10 10 a 10 10 are springs which surround the guiderods and tend to withdraw the punches from the tape.

The punches P and R pass loosely through the plate w, but. carry fixed collars 19 r which bear upon said plate. When the central punch S is operated by the striker S, as hereinafter described, it punches acentral hole in thetape, and the punches PR remain inoperative. .When either of the punches P or R is operated, it punches a hole on one or other side of the central longitudinal When the electromagnet I is energized by the currents received from the line or cable sections and moves its armature i out of the path of the pina", the clutch-sleeve carrying the cam a is thrown into gear with the collar a on the spindle A. The cam 11 then rotates once for every signaling impulse transmitted to the first line or cable section. At each revolution the cam a operates the striker P through the link 0, causing said striker to operate the punch P, and with it the punch S, thus perforating the tape with a hole corresponding to a positive impulse and also making the central perforation. For signals of opposite polarity the cam b is similarly released by the electromagnet I and, rotating, operates the link q and striker R, causing the said striker to operate the punch R, and with it the punch S, thereby perforating a hole on the opposite side of the tape corresponding to an impulse of opposite polarity andat the same time making the necessary central hole.

When the striker P is operated as above described, the arm o of the lever 0 moves the link a) and rocks the lever 17. The lever 4) moves the levers V and V, thereby causing the projection to be movedinto the path of the pin m and to thereby arrest the cam m and also rocking the lever 11. against the tension of the spring "a so as to draw the rod u and the bar U away fromthe wheel T, thus causing the bar U by engaging the pins t I? to lift the pawls 25 11 out of engagement with the wheel T. When thus disengaged from its pawls, the wheel T is returned in the direction of the arrow by the spring t until the stud t strikes the stop i When the striker R is operated, the levers V and V are operated in the same manner through the intervention of the arm q of the lever Q, the link '0 and the lever n When no signals are received, the strikers P and Band the various levers connected therewith are returned to the positions shown in Fig. 1 by the springs 0 if, if, and (1 the projection 11 being moved out of the path of the pin m During the intervals between the receiving of impulses or series of impulses the cam on rotates and at each revolution operates the striker S, thereby causing the punch S to continueto perforate the central line of holes IIO , ient device.

in the tape,and thus obtain the correct spaces between thcimpulses orsignals. Every time the cam m operates the striker S the lever 3 (through the link 8 and lever 15) turns the pivott about its axis, and thereby operates the pawl 15*, thus moving the wheel T in the opposite direction to that indicated by the arrow in Fig. 1, the pawl i preventing any return movement of the wheel T. After a definite number of strokes of the striker S (which number will correspond to the number of teeth on the wheel T) have been given the stud 75 will strike the arm of the lever V, which is arranged to lie in its path, thereby moving the projection 0 into the path of the pin m so as to stop the cam m and prevent an inconvenient length of blank strip or tape being manufactured after the cessation of the receipt of signals. As previously described, when the first signal is received the pawls will be released from the wheel T, and the stud i 'will then be returned to the stop 25 by the spring t.

Referring to Fig. 2, the shaft N is caused to continuously rotate, preferably by an electromotor provided with suitable means for regulating its speed, such as a centrifugal governor arranged to break the electrical circuit of the motor except through a shunt of suitable resistance or by'any other convenn is a gear-wheel, which is mounted on the shaft N and gears with other gear-wheels 47. 01*, mounted, respectively, on

the spindles A and B. As the shaft N rotates, therefore, the spindles A and B and the spindle M are caused to continuously rotate in the required direction.
